Hikvision, is there a recording on the surveillance?

Hikvision surveillance has a recording.

Choose the camera first. When the monitoring system of the network scheme and the simulation scheme are done together, if there is a demand for video recording, you must choose a network camera with camera function.

There are two kinds of cameras with camera function: one is a product with its own camera, and the other is a product that provides an interface and can be externally connected with a camera.

1. First of all, it depends on whether your hard disk video recorder supports 8 audio and 8 video inputs. If yes, each video has a corresponding audio, which can be connected to the hard disk video recorder one-to-one, so that audio and video can be recorded synchronously. ;

2, pickup wiring: one is centralized power supply, then the pickup wiring is a three-core wire; The other kind of pickup is powered separately, so the wiring of the pickup is laid in two cores, and the wiring of the pickup is separated as much as possible. Don't use the same cable tray with strong current such as alternating current to avoid interference from strong magnetic current. ;

3. Wires used: short-distance transmission of audio signals (tens of meters), you can use ordinary pure copper network cable or telephone line. If it is a long-distance transmission, a shielded RVVP line should be used. ;

4. Power supply for pickup: use 12V transformer and pickup to get power. Try not to use the power supply with camera to reduce some interference; Switching power supply is also not recommended, because switching power supply will produce AC noise, which will seriously affect the pickup effect.
